After having played with wikis using wetpaint and PBWiki, and looking at some of the others (Wikispaces, StikiPad), I know that I know more about them than I did before.  But there certainly are a lot of features available if you care to delve more deeply.  Initally I thought PBWiki was easier to use (although adding my first page was not as straightforward as I thought it would be) but after having looked more closely at wetpaint, I think I like the way it is organized more.  I can now see how this tool could be used by a group of students working on a class assignment for example.
